The M3 has undergone significant evolution over the years, with each new iteration bringing something new to the table. From the brilliant widebody E30 of the eighties to the exotic sounding V8-powered E9X, each generation has its own identity but holds true to the goals of providing an amazing driving experience. The G8X gets one of the most potent engines produced by BMW to date, the S58B30, along with an option for AWD. Enhancing the S58 was something we set our sights on soon after acquiring a G80 of our own, the first project being our air intake system. Airbox volume, shape, and construction material all play a part in delivering maximum airflow to your engine. Our engineering team created extremely precise rotational-molded thermoplastic airboxes that eliminate restrictions, supply maximum cool-air entry via two additional ports that open to the wheel wells, and improve engine bay aesthetics. The use of thermoplastic material ensures the air intake system will incur minimum engine bay heat soak and provides unmatched durability for years of service in the harshest environments. Our airboxes were designed using the latest in 3D printing, CAD modeling, and flow bench technology. As a result, we reduced air intake restriction by 13 percent on the driver-side intake tract and 22.8 percent on the passenger-side intake tract. For proper filtration, this kit includes dual high-flow oiled air filters which provide improved filter surface area and improved airflow over the stock panel filters. In addition to the flow benefits, our intake system provides a significant amplification of turbocharger spool and bypass valve venting. These enhanced sounds provide a new level of enjoyment, adding to the incredible driving experience you expect from a BMW M-Series. The Mishimoto 2021+ BMW G8X M2/M3/M4 Performance Intake is a complete bolt-on kit and includes all necessary components for an easy installation.
